Answer:
7 miles
Step-by-step explanation:
Let's call the distance between the library and police station x. Then, the distance between the police station and fire station would be 3 less than twice x. Twice means multiply by 2 so twice x is 2 * x = 2x and 3 less than means that you subtract 3 so 3 less than 2x is 2x - 3. Now, we know that x = 5 so all we have to do now is substitute x = 5 into 2x - 3, therefore, the answer is 2 * 5 - 3 = 7 miles.

Step-by-step explanation:
Answer:
The half life of the substance is approximately 346.6 years
Step-by-step explanation:
Recall that the half life of a substance is the time it takes for it to decay to half its initial value. That is, based on the formula:
the time it takes for M(t) to reach half of its initial value "700 grams" as per the equation provided. That is 350 grams. So we set the equation that imposes this condition, and solve for the time needed making sure we use logarithms in the process in order to bring the exponents down for the solving:
which can be rounded to about 346.6 years
